VISTA, CA – July 11, 2013 –Omnitek Engineering Corporation (OTCBB: OMTK)
today announced it has been selected by the Puget Sound Clean Air Agency for a pilot project to demonstrate its
diesel-to-natural gas engine conversion technology for drayage trucks serving the Port of Seattle, Washington, in
support of the Port’s Clean Truck Program. The project has a goal of meeting 2007 EPA emission standards for
particulate emissions by 2017 for all drayage trucks serving the Port’s marine container terminals, estimated at more
than 2,000 vehicles.

The company’s diesel-to-natural
gas engine conversion system was selected as the best technology under a competitive grant process for the
agency’s “Piloting Engine Upgrade Technologies in the Freight Mobility Sector” project. Omnitek’s technology
reduces particulate emissions as well as nitrogen oxides and carbon dioxide. The pilot project led by Omnitek Engineering
includes American Strategic Group, trucking fleets and related service providers.

“Converting diesel engines to operate on natural gas offers trucking operators a significant return on investment, with much
lower fuel costs and cleaner combustion. We look forward to working with the Puget Sound Clean Air Agency and our
partners to achieve the goals of the Port of Seattle’s Clean Truck Program and participating in a full-scale conversion
program,” said Werner Funk, president and chief executive officer of Omnitek Engineering.

He emphasized Omnitek’s domestic diesel-to-natural-gas conversion business is ramping up
since the company’s recent EPA approval of its technology for the widely operated line of heavy-duty Navistar DT466E
and DT530E engines. Funk noted the company’s is also focused on other diesel engine model conversion
opportunities to complement its international growth expansion with partners in Asia, Latin and South America,
China and Europe.

“Seattle has already converted its refuse trucks and airport taxis to CNG, so extending the
environmental and economic benefits of natural gas to the Port of Seattle drayage fleet is an innovative approach to
keeping the Port of Seattle competitive in the post-Panamax era of ocean shipping. We think the ability to convert
existing assets is crucial for CNG infrastructure development in the United States,” said Stephen Lambo,
president of American Strategic Group.

Lambo noted that Puget Sound is a key cargo gateway between Asia and the United States, with one in
three jobs in Washington State tied to international trade.
